TOOL.

App1ication led October 27, 1915.

To all whom t may concern.'

Be it known that I, ELI YOUNG, a citizen' of the United States, residing at Bowman, in the county of Placer and State of California, have invented certain new and useful Improven'ients in Tools, of which the following is a specification.

The present invention is designed for attaching tool elements to handles, whereby one handle may readily serve for the purposes of a number of different tools. The combination of elements which I term, for the purpose of this description, the attaching means, permits of quick attachment and detachment of the tool element from the handle, yet forms a positive interlocking or interengaging instrumentality insuring against accidental displacement of the tool element in use.

For a full understanding of the present invention reference is to be had to the following description and the accompanying drawing, in which Figure l is a side elevation of a hammer provided with the attaching means which constitutes the subject-matter of this invention. Fig. 2 is a sectional view disclosing` more clearly the disposition of the several elements of the device. Fig. 3 is a vertical sectional View on the line 3-3 of Fig. 2.

, Fig. 4 is a perspective view of the handle engaging member and its end cap. Fig. 5 is a perspective view of the actuating means or wedge member. Fig. 6 is a perspective view of the locking plate. Fig. 7 is a plan view of the connecting means for the tool elements.

Throughout the following detail description and on the several figures of the drawing, similar partsware referred to by like reference characters.

I/Vhile the drawing discloses the application of this invention to a hammer tool element, it is to be understood that I do not wish to be confined to any particular tool in carrying out the object of this invention. rTherefore, in referring to the hammer head as the tool element, such term is to be understood as broadly referring to any particular tool member that it may be desired to attach to the handle. Vith this in mind, the numeral l designates a handle and. 2 the tool element or hammer head in this case. The tool element contrary to the usual construction is preferably made solid or without the customary eye whereby it is positioned upon Specification of Letters Patent.

the extremity of the handle member. Instead, the tool element is provided with a connecting means comprising a U-shaped strap 3 engaging about the tool element but being provided with side members 3 which extend longitudinally of the handle when in attached position and each of which terminates in a hook il. The tool element is preferably suitably grooved to receive the strap 3 so as to provide for the disposition of the strap in such a manner that the surface of said strap will be fiush with the surface of the hammer, as shown by reference to Figs'. l and 2 of the drawing. VThe strap is preferably designed to be a permanent fixture of the tool element though not necessarily so, and as such to be securely fastened by means of a rivet or fastening member 5 extending transversely of the tool element and through a recess G formed therein.

, As will be apparent by reference to the drawing, the tool element is designed to be detachably connected to the handle end, and this is accomplished in the embodiment disclosed by the drawing in the following manner. The handle extremity is provided with a ferrule or engaging member 7 which is attached to the handle by means of a screw or similar fastening member S passing through a cap plate 9 disposed at the end of the handle. The hooked extremities 4e of the side members of the strap member or connecting` means for the tool element are adapted to be engaged with the ferrule 7, the latter being suitably notched at one end as indicated at 10 to receive the hooked extremities. At the other end, the ferrule is provided with an annular shoulder ll which is cut away as at l2 to receive the side members of the connecting strap 3. To cause interlocking engagement of the connecting member 3 with the ferrule, as above mentioned, a wedge 13 is interposed between the tool element and the handle extremity so that when the latter is driven home the tool element is actuated and the hooks el engaged in the notches 10 of the sleeve or ferrule 7. To prevent any liability of the wedge becoming displaced during use of the tool and thereby causing accidental detachment of the tool element from the handle, I preferably dispose a locking member or plate between the handle and the tool element, as shown at 14. This plate is of bendi* able material, and one end thereof is bent to engage with the tool element 2 while the IGF) vopposite end is bent in the'opposite direction into engagement with the larger end of the wedge.v This provides a positive interlocking connection as will be apparent and will prevent any tendency ofthe wedge to work out of its operative position holding the tool element upon the handle. It is within the purview of this invention to provide, if desired, a connecting member or bolt to pass through the sides 3 so as to hold these sides in clamped position, and when such is used, the handle and the side members would be provided with openings to receive the bolt, which not beingv a necessary element is not illustrated in the drawing.

It will be obvious that the foregoing arangement provides for a very rigid and positive connection of a tool element to a handle member and when it is desired to supply said handle with a different kind or another tool element, it is only necessary to bend the locking plate extremity away from the wedge whereupon the latter may be displaced and the interlocking connection of the strap 3 disengaged. The tool to be attached will preferably be supplied as here- `inbefore premised with the necessary connecting strap 3 and said tool element may be quickly attached in the reverse manner to that just described for the removal.

One of the advantages of a hammer implement of the construction herein described is that the end surface is Hush and may be utilized for hammering with a direct movement of the implement longitudinally of the handle, the omission of the eye from the hammer head providing additional weight for the hammering function.

Having thus described my invention, what I claim as new is:

l. In combination, a handle, a tool element adapted for attachment thereto, a handle engaging member, connecting means formed with locking elements cooperating with -the tool element and adapted for detachableinterlocking engagement with the handle engaging member, and means insertible between the tool and the handle for actuating the tool to cause movement of the connecting means therewith relative to the .handle and incidental thereto the interlocking engagement'.

n 2. In combinatioina handle, a tool element adapted for attachment thereto, a handle engaging member, connecting means cooperating with the Vtool element and adapted for interlocking engagement with the handle engaging member, means for actuating Vopiefs of this patent may Vbekobtained for the tool to cause the interlocking engagement, and a locking member interposed between the tool element and the actuating means and cope'ating with the actuatingmeans aforesaid at one end and the tool element at the other end to prevent accidental displacement of the former.

3. In combination, a handle, a tool element adapted for attachment thereto, a connecting strap mounted on the tool clement and having hooked terminals for engagix'lg the handle, and wedge means adapted to actuate the tool with respect to the handle when inserted between the latter and the tool element to .cause engaging action of the hooked terminals.

4l. In combination, a handle, a tool element adapted for attachment thereto, a connecting strap mounted on the tool element and having hooked terminals for engaging the handle, wedge means adapted to actuate the tool with respect to the handle when inserted between the latter and the tool element to cause engaging action of the hooked terminals, and locking means intermediate the handle and the tool element and coacting with the wedge means to lock the same from accidental displacement.

lIn combination, a handle, a ferrule disposed at one end thereof, means connecting said ferrule to the handle, a tool element, a strap member mounted thereupon, said strap member being U-shaped in formation and having its side members formed with hooked terminals adapted for engagement with the ferrule aforesaid, and a wedge insertible between the handle and the tool element for causing interlocking engagement of the hook members with the ferrule as above mentioned.

(i. In combination, a handle, a ferrule mounted at one end thereof`l a cap member engaging the end of the handle and the ferrule, connecting` means securing said cap member to the handle, a tool element, connecting means engaging the tool element for connecting the same to the handle, the ferrule aforesaid having notches to receive the connecting means, wedge means insertible between the handle and the tool element to cause interlocking engagement of the connecting means and the ferrule, and a locking member coacting with the tool element and the wedge member to prevent accidental displacement of the latter.

In testimony whereof I aiiix my signature.
